The problem in the picture would be
x^2+10x+21
Recall that
Pressure = Force ÷ Area
In this context we have,
Pressure = 24,000 ÷ (16 × 12)
= 24,000 ÷ 192
= 125 Pa
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:
<span>[(4x + 15) / 5x)] = 1/2 could be written as:
4x + 15 1
----------- = ---
5x 2
Then 8x + 30 = 5x
3x = -30, and so x = -10 (answer). Be certain to check this answer through substitution!

Angles 5 and 6 are not congruent because they are on the same line, so the answer is I
<h3>The volume of cube is 729 cubic centimeter</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>

Where, "a" is the length of side of cube
Given that, surface area = 486 square centimeter

<u><em>Find the volume of cube:</em></u>

Thus volume of cube is 729 cubic centimeter
